Tools

Tools allow the LLM to perform actions in your codebase. TF Code comes with built-in tools and supports MCP servers and custom tools via plugins.

Configure

Use the permission field to control tool behavior — allow, deny, or require approval:

{
  "permission": {
    "edit": "allow",
    "bash": "ask",
    "webfetch": "deny"
  }
}

Wildcard patterns:

{
  "permission": {
    "mymcp_*": "ask"
  }
}

Tool	Description	Permission Key
`bash`	Execute shell commands	`bash`
`edit`	Modify files using exact string replacements	`edit`
`write`	Create new files or overwrite existing	`edit`
`read`	Read file contents	`read`
`grep`	Search file contents using regex	`grep`
`glob`	Find files by pattern matching	`glob`
`apply_patch`	Apply patches to files	`edit`
`skill`	Load a skill and return its content	`skill`
`todowrite`	Manage todo lists during sessions	`todowrite`
`webfetch`	Fetch web content	`webfetch`
`websearch`	Search the web for information	`websearch`
`question`	Ask the user questions during execution	`question`
`lsp`	Interact with LSP servers (experimental)	`lsp`

Note: write and apply_patch are controlled by the edit permission key.

Globally:

{
  "tools": {
    "write": false,
    "bash": false
  }
}

{
  "permission": {
    "edit": "deny"
  },
  "agent": {
    "build": {
      "permission": {
        "edit": "ask"
      }
    }
  }
}

Agent permissions override global settings.
